Did you apply all 4 patches?

Intel replaced the mess that was BIOS with an even worse horrendous OS called EFI. Now we have to work with the garbage they force upon us.

Sure did.
The only thing I've done differently is where I've been extracting the sources, instead of /usr/src, everything is done from a directory in my home directory. Even the linux link is within that structure. All the patches apply without error, and the build goes without error, packages build and install fine. As I said it all boots fine. When the rtai modules are built, after a reboot, everything builds without error, packages install fine and cd into the the testsuite directory the test runs without error.
Had the same thing with the -173 build but now on the -174 build.
So it looks like the RTAI may not be an option for boards that are a pure (without csm/legacy option) UEFI boot ?

Yes, for now.
Intel has had a better option for 20 years. They could have used coreboot/LinuxBIOS. But our PC's have to be secure from us so we have EFI.

Ok cool thanx.
The reason i thought it was a config issue on my behalf, sorry if I didn't make that clear, is generally I'll point blame at myself first before looking for others to blame.

www.linuxcnc.org/temp now contains a set of 4.14.174 packages for for kernel, rtai and linuxCNC.
This _should_ support i915 Intel graphics, unless I messed it all up.

I am still restricted to 1024x768, do I need to install more than just the linux-image?
Boot to a console and try Xorg -configure:

Downloaded the package and it's not there.
If enabled in config it should be here
/lib/modules/4.14.174-rtai-amd64/kernel/drivers/gpu/drm/i915
I've built both -173 & -174 with intel i915.
On my test machine if I set it up for intel graphics the modules are loaded and I get full resolution. This is a T530 with Optimus disabled.
Only issue I have is the when booting using UEFI only one core is reported.....Legacy boot has both cores there. Trying to get an answer on the RTAI mailing list.

I am a bit puzzled, but it does seem that the i915 support was not enabled. Also missing (and probably an annoyance only to me) was the VMWare support, which explains why the VM on my Mac has such low resolution.
I am building a new version.
